and the signs of DAD and no signs of suppurative bronchopneumonia are reported histologically. In patients who died from COVID-19, autopsy studies revealed pneumonia from 0 to 48% of cases (17) (18) (19) . Finally, the histopathological findings in the lung of patients who died of COVID-19 are similar to those described in Middle East respiratory syndrome coronavirus (MERS-CoV) (22,23), suggesting similarities in the pathogenesis and the mechanisms of lung tissue damage.

In conclusion, the rivisitation of the pneumonia in patients who died of COVID-19, revealed a discrepancy between the CT signs identified as "pneumonia, COVID-related" and histology. Lung histopatologic fetures are mainly related to ADA and/or associated with PE and a conseguent respiratory failure causing death in COVID-19 patients.

These knowledge are essential to improve the clinical approach and to reduce mortality in COVID-19

patients.
